I'm using apalike-letters bibliography style which inserts heading for each first letter of authors' names. It works well for English letters but when a name starts with Polish letter it starts to get crazy. Consider following example:

Note that the order of the items is correct (Ł should be after L and Ś should be after S) but first letters of Łuszczewski and Śpiewak are replaced with their second letters.

I think that it is caused by purify function which strips non-alphanumeric characters from string (and Ł and Ś are not treated as alphanumeric) but I don't know how to change this. All I managed to do is to change Ł to \L but then Łuszczewski was inserted in L section which is not correct.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

I don't think that you can use this style with initial other than plain latin characters. I tried to use bibtex8, but it fails.

Although you don't want to hear this (I know you mentioned problems with it in your previous question), but I really think you should try to get this working with biblatex and biber which have much better methods for sorting non-English alphabets.
